Revert the Codec Kit.

All of Barrett's individual reverts have been squashed into this
one commit, save a few actual bugfixes.

Change-Id: Ib0a7d0a841d3ac40b1fca7372c58b7f9229bd1f0

media_kit: Remove most private dependencies from codec_kit

* Move to BCodecKit namespace and make extensive use
of BCodecRoster.
* This is a first step in the right direction of
decreasing private dependencies. Some APIs are being
translated to the CodecKit. I am doing an investigation
on which APIs are really used among apps, so that the new
kit can be more slim and oriented toward easy development
and can be extended in the right direction instead to
continue maintaning unuseful code.
* BMediaFormats needs still a bit of love.
* General improvements in style and code maintainability.

Media Kit: Update private code

MediaFile/MediaTrack: Use MetaData API internally

MediaFile/MediaTrack: Use metadata to retrieve copyright

MediaTrack: gaurd printf's behind TRACE_MEDIA_TRACK

MediaTrack: Calling debugger() crashes the program

So, call printf instead, which allows the program to print an error
rather than crashing.

MediaTrack: Style fixes

64 bit fixes for libmedia.so, ActivityMonitor, and Sudoku.

* Alex, I feel your pain :-)

gcc 4.5 build fix

* Change the signature of the Writer plugins setup methods such
that they can modify the media_format passed in. For example they
can store information in the user_data section. I don't actually
use this anymore, but it may come in handy again.

AVFormatWriter:
* Adjust the AVCodecContext flags not only for video, but also
for audio streams (as the API example does). This mechanism
may not yet work, since the AVCodecEncoder actually uses a
different AVCodecContext instance.
* Use the encodeInfo->flags and specify the key frame flag
for the AVPacket. This finally makes videos encoded on Haiku
seekable.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@39035 a95241bf-73f2-0310-859d-f6bbb57e9c96

Finall changed the Seek() method of Decoder plug-ins to
SeekedTo(), since it's only informative to decoders. They
can't modify the seeked frame/time. This also mirrors what
all existing decoders were doing in Seek(). BMediaTrack
is simplified accordingly (resolved two TODOs).


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@38705 a95241bf-73f2-0310-859d-f6bbb57e9c96

Implemented an API to get arbitrary meta-data about
BMediaFiles and about BMediaTracks in BMessages. As an
example, one can get chapter meta-data or the language
name of an audio-track.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@38685 a95241bf-73f2-0310-859d-f6bbb57e9c96

Resolved TODO. The current time should point to
the beginning of the next buffer. GetNextChunk()
still has the same problem.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@38544 a95241bf-73f2-0310-859d-f6bbb57e9c96

Of course the same fix needs to be applied
to SeekToTime(). The extractor may have
modified the time, don't let the decoder
overwrite the actually seeked time. I am thinking
the API should be called SeekedTo() or Seeked(),
and would be purely informative for decoders,
without even a return value.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@38499 a95241bf-73f2-0310-859d-f6bbb57e9c96

Do not override the seek frame which the extractor may
have adjusted. (The API is somewhat silly, since Decoders
can't really do anything with the seek frame, it can only
be told to them. But current decoders will assign the seeked
frame from the wanted frame, which would override the seeked
frame from the extractor... the API should be fixed.)


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@38496 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Renamed _plugin_manager to gPluginManager.
* Improved tracing in PluginManager.cpp when loading an add-on.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@38330 a95241bf-73f2-0310-859d-f6bbb57e9c96

Closes #6349

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@37670 a95241bf-73f2-0310-859d-f6bbb57e9c96

Reverted some of my changes with regards to fCurrentTime and added respective
TODOs. For now, it is easier for applications to work around the status quo
until the TODOs are implemented.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@35032 a95241bf-73f2-0310-859d-f6bbb57e9c96

It's late, forgot to remove debugging output...


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@34924 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Indentation and naming cleanup in the header
* Small coding style cleanups in the .cpp
* When reading raw chunks, keep fCurrentFrame updated anyway
* When decoding frames and chunks, don't change the meaning of fCurrentTime,
it's supposed to be the start time of the next chunk/frame, same as
CurrentFrame(), not the time of the frame/chunk we just decoded/read.
BMediaTrack::CurrentFrame() is actually documented like this in the BeBook,
but CurrentTime() is not. However, when seeking to a specific time, it is
understood that this is the time of the next frame/chunk. If we decode/read
it and set fCurrentTime to the start_time as specified in the media_header,
it would actually not change for the first frame/chunk after seeking.
To be able to know the duration of chunks, fWriterFormat had to be changed
to just fFormat and is now used for decoding as well.
* Simplified handling of media_header in some methods, saves one assignment.

These changes are not so well tested, yet.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@34923 a95241bf-73f2-0310-859d-f6bbb57e9c96

Fixed last minute change that I apparently didn't compile. Sorry.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@32125 a95241bf-73f2-0310-859d-f6bbb57e9c96

Encoder:
* Fleshed out the Encoder API to support parameter setters/getters and returning
a BView for configuration. (Not yet sure if this is a good idea.)

BMediaTrack:
* Implemented all but one of the unimplemented methods in BMediaTrack. It should
be working as far as that class is concerned, unless I missed some of the
vision. ReplaceFrames() remains a stub, added a comment on why it probably
stays that way.
* Release the Encoder reference in the destructor.

FFmpeg plugin:
* Refactoring to delay opening the AVCodec until encoding the first chunk,
so that we can still adjust parameters.
* Support adjusting parameters via [Set|Get]EncodeParameters(). Currently,
only quality is supported, added TODOs about supporting the bit_rate setup
versus the automatically calculated bit_rate.
* Extended EncoderDescription by a bit_rate scale. The Encoder calculates the
raw bitrate needed by the current media format, and then divides that
number by the specific codec's bit_rate_scale, while taking into account the
desired quality. This seems to work very well already (tested with MPEG4),
although a lot more parameters could be specified for libavcodec, depending
on the desired quality.
* Enabled the ogg muxer in libavformat, although it is currently still disabled
in MuxerTable.cpp, because it rejects unknown codecs. Added TODO to this
effect.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@32124 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Tweaked the Writer API. Basically, we need an Init() method that takes the
media_file_format as input, so that the Writer knows what kind of file is
needed.
* Also, since information about the stream format is going to be needed at the
Writer level as well, the AllocateCookie() method gets the stream
media_format.
* Fleshed out some aspects of AVFormatWriter, many TODOs are left.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@32025 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Writer::WriteChunk() takes media_encode_info* instead of flags.
* Improved Encoder API towards what we need for the get_next_encoder() variants
and the BMediaTrack API.
* Implemented the rest of MediaWriter. Still undecided what to make of
AddTrackInfo(). BMediaEncoder has that as well, which hints that this is
something the Encoder needs to support. But it could also be that this is
only possible to support in Writer.
* Wired a lot of previously unimplemented methods in BMediaFile and BMediaTrack
needed for write support. If I have not overlooked anything, only the
parameter stuff is still unimplemented now.

This is all untested, since the FFMpeg Encoder and Writer are still only stubs.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@32013 a95241bf-73f2-0310-859d-f6bbb57e9c96

Cleanup and preparations for BPrivate::media::MediaWriter, which will soon
exist.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@31983 a95241bf-73f2-0310-859d-f6bbb57e9c96

* As suggested by Axel, BMediaTrack::GetCodecInfo() don't anymore say
"Haiku Media Kit: ", as it's given for any caller of a Media Kit API ;-)
* This remove an systematic line feed in the codec pretty name returned;
* Updated MediaPlayer info window text layout to take this change into account.




git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@29836 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Use NULL instead of 0 for some pointer initializations.
* Slightly more debug output for failed atempts to create a decoder.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@25825 a95241bf-73f2-0310-859d-f6bbb57e9c96

Add char * version of ReadFrames, for compatibility with some R5 games.
Patch by genki0. I didn't see any reason not to commit it, so...
This should fix #897.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@25656 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Added FindKeyFrame() method to MediaExtractor, it is similar to Seek(),
but operates "read-only".
* Added FindKeyFrame() method to ReaderPlugin, see above.
* Reformated ReaderPlugin header. Added const qualifier to Source() method.
* Small cleanups in BMediaTrack::SeekToTime() and SeekToFrame(). Added TODOs
with regards to "seeking" in decoders, wich should IMHO be revised. (Codecs
cannot seek in the stream, they only get fed chunk data. The only thing they
can do is reset themselves in preparation for a discontinuity of the chunk
data...)
* Implemented BMediaTrack::FindKeyframeByXX() methods via the new
MediaExtractor::FindKeyFrame() method.
* Implemented Seek() and FindKeyFrame() methods in the Reader base class,
returning B_NOT_SUPPORTED. I think this makes sense and also I don't have
to adapt all existing Reader plugins for the new FindKeyFrame() call. :-)
* Implemeneted FindKeyFrame() in the avi_reader. The OpenDMLFile class
gets Seek() extended for a "read-only" mode. Currently the implementation
is broken (as before) with regards to keyframes. These were ignored before
and I have not changed them to actually support the seek flags with regards
to keyframes. That's the interesting TODO...
* Some reformatting here and there in avi_reader code, sorry for the mixup.
The only actual change is the support for the read-only flag to Seek().

Failing to find a suitable decoder for a stream is reported in three different
modules, I left the one from MediaExtractor::CreateDecoder, since it also
mentions the stream index.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@24491 a95241bf-73f2-0310-859d-f6bbb57e9c96

Return B_ERROR for the FindKeyFrameFor*() methods, unless the time/frame
is 0, in which case it is almost save to assume it is a keyframe. Added
TODO though.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@24474 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Use tracing facilities in BMediaTrack.
* Turn off tracing in the Media Kit.
* Notify of unimplemented functions regardless of tracing.

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@16466 a95241bf-73f2-0310-859d-f6bbb57e9c96

Media Codec API just got a visit from the coding style police.
We now use "const" for the chunk buffer pointer returned by GetNextChunk,
because the buffer is not supposed to be modified by the codec.
size_t is used for the size where applicable. This matches BMediaDecoder.

When the decoder doesn't support the requested format, the raw decoder is utilized
to provide a format conversion to the requested raw format.
Added a few workarounds for applications that don't requst the required format

* Wired a lot of previously unimplemented methods in BMediaFile and BMediaTrack
needed for write support. If I have not overlooked anything, only the
parameter stuff is still unimplemented now.

This is all untested, since the FFMpeg Encoder and Writer are still only stubs.

Cleanup and preparations for BPrivate::media::MediaWriter, which will soon
exist.

* As suggested by Axel, BMediaTrack::GetCodecInfo() don't anymore say
"Haiku Media Kit: ", as it's given for any caller of a Media Kit API ;-)
* This remove an systematic line feed in the codec pretty name returned;
* Updated MediaPlayer info window text layout to take this change into account.

* Use NULL instead of 0 for some pointer initializations.
* Slightly more debug output for failed atempts to create a decoder.

Add char * version of ReadFrames, for compatibility with some R5 games.
Patch by genki0. I didn't see any reason not to commit it, so...
This should fix #897.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@25656 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Added FindKeyFrame() method to MediaExtractor, it is similar to Seek(),
but operates "read-only".
* Added FindKeyFrame() method to ReaderPlugin, see above.
* Reformated ReaderPlugin header. Added const qualifier to Source() method.
* Small cleanups in BMediaTrack::SeekToTime() and SeekToFrame(). Added TODOs
with regards to "seeking" in decoders, wich should IMHO be revised. (Codecs
cannot seek in the stream, they only get fed chunk data. The only thing they
can do is reset themselves in preparation for a discontinuity of the chunk
data...)
* Implemented BMediaTrack::FindKeyframeByXX() methods via the new
MediaExtractor::FindKeyFrame() method.
* Implemented Seek() and FindKeyFrame() methods in the Reader base class,
returning B_NOT_SUPPORTED. I think this makes sense and also I don't have
to adapt all existing Reader plugins for the new FindKeyFrame() call. :-)
* Implemeneted FindKeyFrame() in the avi_reader. The OpenDMLFile class
gets Seek() extended for a "read-only" mode. Currently the implementation
is broken (as before) with regards to keyframes. These were ignored before
and I have not changed them to actually support the seek flags with regards
to keyframes. That's the interesting TODO...
* Some reformatting here and there in avi_reader code, sorry for the mixup.
The only actual change is the support for the read-only flag to Seek().

Failing to find a suitable decoder for a stream is reported in three different
modules, I left the one from MediaExtractor::CreateDecoder, since it also
mentions the stream index.

Return B_ERROR for the FindKeyFrameFor*() methods, unless the time/frame
is 0, in which case it is almost save to assume it is a keyframe. Added
TODO though.

* Use tracing facilities in BMediaTrack.
* Turn off tracing in the Media Kit.
* Notify of unimplemented functions regardless of tracing.

Media Codec API just got a visit from the coding style police.
We now use "const" for the chunk buffer pointer returned by GetNextChunk,
because the buffer is not supposed to be modified by the codec.
size_t is used for the size where applicable. This matches BMediaDecoder.

When the decoder doesn't support the requested format, the raw decoder is utilized
to provide a format conversion to the requested raw format.
Added a few workarounds for applications that don't requst the required format
but instead assume to get a specific one.
